Ask HN: Any good resources on memory management in Canvas+Javascript apps?

I've found a few decent resources on Javascript and best practices in terms of memory, but not a whole lot specifically about how best to build applications using Canvas and to minimize the memory overhead. The most directly applicable knowledge I can find mainly relates to how JS and DOM elements work together in terms of memory leaks.

There are a few StackOverflow questions I've come across that address specific issues with specific implementations, but nothing in a unified resource that can be used as a point of reference for general development.

Maybe the issue is that Canvas is "too new", and such resources simply don't exist yet, but I'd be very eager to get any and all feedback on the issue from the good folks here at HN.

Thanks in advance.
